So do you need to buy the hangers separately as part of the exhaust upgrade?

The car feels way smoother along the power line after the tune. I had OFT but decided to contact Steve99 and I couldn't have made a better choice. As as an specific HP number I couldn't tell you. I've never taken the car to the Dyno, so I could only guesstimate. I want to say around the 190 ish HP?
The hangers are purchased separately. I got mine from Nengun, took about a month.
